SA-G or HA, potentially impacting the scaffold's stability [45]. The changes observed in the SA-G component further underscore the impact of crosslinking. The shift in the C = O peak from 1409 cm-1to 1395 cm−1after CaCl2treatment suggests ionic bonding between Ca2+and the COOH g...
Following microwave treatment, the polar functional groups of sodium alginate and sodium carboxymethyl cellulose (i.e., OH, amide-I, and amide-II) may interact via hydrogen bonding [96], forming a compact structure. Moreover, the strong interlinks between the polymer chains cause the polymer ...

The more rigid protuberances penetrate the deformable counterpart, thereby forming individual points of actual contact, where attachment forces arise (adhesion, chemical bonding, interdiffusion, and so on). As a result of wearing-in, the points of contact become “elongated” in the direction of ...
In addition to the preserved crystallinity and porosity, we also confirmed that the bonding between metal ions and organic linkers in MOFs remain intact before and after patterning. Supplementary Fig.22compares the FTIR spectra of pristine MOFs films, MOF films containing bisazide crosslinkers before...
Therefore, there are some efficient approaches for increasing heat dissipation, like stretching the polymer films to gain higher polymer orientations, or introducing the hydrogen-bonding interactions between neighboring chains which are about one magnitude stronger than the van der Waals interactions [43,...
The stretching vibration of the –NH2 and –O–H at 3300–3500 cm−1 is strong broad band and decrease in this band transmittance after adsorption of some metals indicated that the bonding of metals with –NH2 group. Thus, the main adsorption site for metals adsorption on the CS-ECH is...
“Neck bonding” refers to the process wherein an elastic member is bonded to a second member (facing) while only the second member (facing) is extended so as to reduce its dimension in the direction orthogonal to the extension. Such materials generally have cross-machine direction stretch. As...
The key to achieve such a high-yield lift-off was that ZnO nanotubes were grown on top of graphene layers, and graphene films had a very weak bonding with the underlying substrate. The maximum number of ZnO nanotube array we lifted-off was 500 × 500 array in 2 × 2 mm2 area (see ...
Any engineered wood product (EWP) results from the union of any of these raw materials by bonding (resins) or fixing (screws, plugs, dowels, etc.) to obtain a stable structural solid timber [6,48]; From timber products, plant production of timber buildings is possible through prefabrication...
